Baijiu is the national liquor of China and the world's most consumed spirit, which is produced using a unique and traditional solid-state fermentation (SSF) process. The development of an automatic and intelligent technology for SSF is more difficult than that for liquid-state fermentation. However, the technological upgrading of the SSF process is crucial for reducing the labor intensity, saving manpower, avoiding the waste of materials and energy, and providing a favorable operation environment for workers; moreover, it provides a great reference value to similar industries. This article reviews the latest application progresses in automatic and intelligent technologies for Baijiu production. The important technical processes are introduced successively, including the production of Jiuqu, SSF, solid-state distillation, storage, and blending. The bottlenecks and challenges are pointed out for automatic and intelligent upgrading of these technical processes. Furthermore, the typical technology application cases in an integrated automatic production line of Baijiu are also summarized. Next, the industrial development status of Baijiu production is compared with those of other liquors in the world. Finally, future development directions are proposed. This review will provide an overall introduction and objective analysis of recent developments and current challenges in Baijiu manufacturing so as to promote the intelligent brewing of Baijiu.
白酒是中国的国酒，也是世界上消费最多的烈酒，它采用独特的传统固态发酵（SSF）工艺酿造。固态发酵自动化和智能化技术的开发比液态发酵技术更具难度。然而，固态发酵工艺的技术升级对于降低劳动强度、节省人力、避免物料和能源浪费以及为工人提供良好的操作环境至关重要；此外，它对类似行业具有很大的参考价值。本文综述了白酒生产自动化和智能化技术的最新应用进展。依次介绍了重要的工艺流程，包括酒曲生产、固态发酵、固态蒸馏、储存和勾兑。指出了这些工艺流程自动化和智能化升级的瓶颈与挑战。此外，还总结了白酒综合自动化生产线中的典型技术应用案例。接下来，将白酒生产的产业发展现状与世界上其他酒类的产业发展现状进行了比较。最后，提出了未来的发展方向。本综述将对白酒制造的最新发展和当前挑战进行全面介绍和客观分析，以促进白酒的智能酿造。
